Problem regarding upload example

[ghost]

Greetings,
I was trying to upload tft file to Nextion with Arduino and a micro SD card module.

#include "NexUpload.h"
NexUpload nex_download("SensaT_V2.tft",53,115200);
void setup() {
  // put your setup code here, to run once:
    nex_download.upload();
}

void loop() {
  // put your main code here, to run repeatedly:
}

And this is the massage I received:

12:04:31.612 -> start _checkFile
12:04:31.612 -> file is not exit
12:04:31.658 -> tft file size is:
12:04:31.658 -> 0
12:04:31.658 -> check file ok
12:04:32.356 -> get baudrate error

I tried different baud rates but It does not work. Any ideas or solutions would be massive help thanks.
